rust-lang/rust#98112 adds unaligned ptr dereference checking (since unaligned refs are UB) in debug mode (-C debug-assertions), which has uncovered further unaligned ptr derefs (I'm not sure how many; it crashes on the first one):

thread 'main' panicked at 'misaligned pointer dereference: address must be a multiple of 0x8 but is 0x7ffdaed2292c', src/lf_mask.rs:217:21It seems this one is from ALIGN_STK_[0-9]+ macros that wrap ALIGN that I missed in #232 since they didn't use ALIGN directly. Once this one is fixed, I'll see if there are any remaining unaligned refs.
